I switched to FireFox as my primary web browser several months back, and during that time I’ve come to love some of the features, such as the Sage RSS reader plugin and tabbed browsing. But in spite of those great features, the browser itself quite literally sucks. It sucks up memory at an unbelievable rate, easily crossing the 100 – 200 mb range after several days of browsing. It sucks up CPU cycles, too, sometimes spinning endlessly between at around 50% usage for no good reason. And then it sucks when it’s time to print anything, causing the browser to hang for periods of time, when it doesn’t just outright crash the browser.
I’ve been waiting for a new version that might improve these features, but if the authors have been believing their own hype, I shouldn’t hold my breath.
